ams OSRAM GW Q9LR33.EM DURIS® S 8 High-Efficacy 5050 High-Voltage LED

Introduction

The ams OSRAM DURIS® S 8 (GW Q9LR33.EM) represents a strategic performance benchmark for manufacturers requiring a balance of intense radiant power and superior system-level efficiency. Engineered with a high-voltage, low-current architecture, this 5050 component allows for more efficient circuit designs. By operating at a higher voltage tier, it reduces resistive heat losses across the PCB traces and facilitates the use of more cost-effective, high-efficiency non-isolated drivers-effectively lowering the overall Bill of Materials (BOM) for large-scale arrays.

For LED module manufacturers and contract manufacturers (EMS), the GW Q9LR33.EM provides an industrial-grade "workhorse" in a robust epoxy molding compound (EMC) package. Built on ams OSRAM's high-power lead-frame platform, this LED ensures that chromaticity stability and lumen maintenance are preserved throughout the product's rated lifespan, making it the preferred light engine for high-bay fixtures and professional roadway modules.

Key Product Features

• Optimized High-Voltage Performance: The 24V class design allows for achieving target wattage with significantly lower currents compared to standard 3V LEDs. This enables the use of thinner copper traces and improves overall driver conversion efficiency.
• Verified Hot-Color Targeting at 85 °C: Unlike budget-grade LEDs characterized only at 25 °C, ams OSRAM bins this series at actual operating temperatures. This ensuring that the chromaticity you specify during the design phase matches the real-world performance once the fixture reaches thermal equilibrium.
• Superior EMC Package Reliability: The specialized 5050 lead-frame is designed to withstand extreme thermal cycling and high-humidity environments. This stability protects the phosphor layer from premature yellowing and maintains a stable CCT over its rated lifespan.
• Excellent Sulfur Resistance: Built with high-quality plating and materials, the DURIS® S 8 series is designed to withstand harsh industrial gases, a non-negotiable factor for municipal roadway tenders and fixtures in high-pollution zones.
• Precision Binning Consistency: Binned within a 3-step MacAdam ellipse, the GW Q9LR33.EM ensures that color variance across large-scale installations is virtually invisible to the human eye.

The GW Q9LR33.PM series is a staple light source for performance-driven markets:

• Industrial High-Bay & Low-Bay: Consistent, high-intensity daylight white sources for warehouses requiring high alertness and long-term maintenance cycles.
• Municipal Street Lighting: High-throw efficacy for roadway infrastructure projects targeting Energy Star® or high maintenance cycle certifications.
• Parking Lot & Area Floodlighting: Durable emitters for wall packs and security floodlights targeting high lumens-per-watt and resistance to environmental stress.
• Specialized Office Troffers: High-lumen density modules where higher voltage strings help in achieving slim-profile driver integration.
